“We are very pleased with the significant growth in our year-end reserves and our continued strong operational results,” said Chief Executive Officer Earl Reynolds. “Our premier STACK assets continue to build economic proved reserves and provide significant long-term drilling opportunities. Although the recent drop in commodity prices has created uncertainty in the market, we remain focused on delivering exceptional operational results and profitable production growth while minimizing costs. We are currently working with our board to finalize our 2019 business plan as we look at various capital program alternatives, which adhere to our strategic objectives of profitably growing production and delivering strong returns through intense focus on execution and costs, while maintaining more than sufficient liquidity. We are confident in our ability to operate in a lower commodity price environment while still creating value for our shareholders.”

Operational Update

Chaparral added a fourth rig during the fourth quarter of 2018 to advance its Kingfisher County King Koopa and Canadian County Merge Foraker spacing tests, as well as progress through the remaining joint venture wells with Bayou City Energy. The five King Koopa wells and the original parent were placed on production throughout December and initial production and pressure indications are encouraging, with limited communication between child wells or the original parent, suggesting Chaparral’s spacing and frac design are working effectively. Initial results for the King Koopa test will be available when there have been a sufficient number of days of production to report. The company is currently drilling the 11-well Foraker full section spacing test in Canadian County and plans to have well results available in the first half of 2019.

Total company production for the full year 2018 was an estimated 20.5 MBoe/d, of which 36% was oil and 25% was natural gas liquids (NGLs). STACK production for the full year 2018 was an estimated 14.5 MBoe/d, an annualized growth rate of 52% compared to 2017, of which 35% was oil and 26% was NGLs. Total company production for the fourth quarter of 2018 was an estimated 21.7 MBoe/d. Fourth quarter 2018 STACK production was an estimated 16.6 MBoe/d, which represents a 60% increase when compared to the fourth quarter of 2017 and a 6% increase compared to the third quarter of 2018.

2018 Year-End Proved Reserves

Chaparral’s preliminary determination of year-end 2018 proved reserves increased 35% from year-end 2017 to 94.8 MMBoe after adjusting for 2018 divestitures, with 34% oil and 27% NGLs. Approximately 57% of the proved reserves were classified as proved developed. The company’s reserve estimates were prepared by third-party reserve consultant Cawley, Gillespie and Associates.

Proved reserves for Chaparral’s STACK assets increased by 49% on a year-over-year basis, from 49.4 MMBoe to 73.7 MMBoe. In the STACK, Chaparral replaced 519% of estimated 2018 STACK production.
